To all whom it may concern.'

. Be it known that L'JAvma Lors BUSTOS, a citizen of the Republic of(Dhile, residing in Santiago de Chile, in said Republic, have inventedcertain new and useful Improvements in Tide-Motors, of which thefollowing lis a specification.

This invention relates to an improved tidemotor, which is operated bythe variations ofthe level of the sea-variaticns which are produced bythe tides along the shore and natural inlets, and in all places wherethe waves do not merely wash' the shore, but -roll at considerabledifferences in their level.

u ',IIlxese fluctuations of level are taken advanf8. roughf'thc mayreach fifteen meters. The

interval o time in which these differences of level may take place issometime's delayed up to eight seconds, but in most cases one may counton an average of four seconds bej tweeii the rising and fallingmovements. 1

Similar reference characters denote corlresp'cnding parte in the figuresof the drawm KVVy apparatus is operated by means of the sea andiscomposed of the ,following mechanisms, a float 1 whose size or capacityis in proportion to the force which is to be degluided by means ofrollers r at. diametrica ly-opposite points along vertical posts 6 and 7that are anchored yinto the bottom of the sea. The top of the float 1 isconnected by a piston-rod 20 kwi'th a pistou 21 of an air-compressingpump 2.l In order to prevent damage to the pump bythe quick rising ofthe sea-level or any interference with the working of the apparatus, ,anautomatic system is used by means B5 of which the action of the pump'isregulated, and which consists of the following instrumentalities: afixed cross-bar l5 which encircles and guides the upper end of thepump-cylinder 2 and a lower cross-bar 14 which is attached te thepump-cylinder and which is locked by two spring-bolts 8 in iti; endsinto notches of the posts 6 and 7. To the top of the float 1 areattached two upright posts 9 having forked upper ends', and w ich engagefulcrumed lever 16, which have the object that, in case of arapid risingof the level of the water, the float, after having made a completestroke of the piston, rises and lifts the pump-cylinder, after firstwithdrawing the spring-bolts from the notches of the posts 6 and 7,preventing thereby injury and damageto the parts. The spring-bolts 8lock the cross-bar 145 of the pump-cylinder into one of the higher pairsof notches of the posts. On the descending of the fio-at 1 the cross-barof the pump-cylinder is released by the withdrawing of the spring-bolts8, which is' accomphshed b a chain 13 connecting the float with a fucrumed lever 11, the forked rearportion of which is connected by chainsl0 with the lower ends of the fulcrumed levers 16. The lever 11 isfulcrumed'to a bracketarm 12 on'A the cross-bar 14, as shown in Fig.

2. The release of the spring-bolts produces a the lowering of the pumpwith the float' until it is returned into its lowermost position withthe falling wave, producing thereby the lowering of the piston ready forthe next compressing action of the same in the pumpcylinder. It isreadily understood that at low tide the float, by its own weight. willllower itself also, so as to lower the piston in the 'pump and suck inthe air into the-"pumpcylinder. As thi-oubli a suction-valve 17 at theupper end of t e ump-cylinder 2 air is admitted when the pistondescends, when Ythe float rises with the level of the water, the

air is compressed in the pump-cylinder and conducted through a flexibletube 3 having a check-valve 18 from the upper end of the pump-cylinderto a receiver 4, the size of which is proportioned with the size of thetide-motor. The compressed air is stored in the receiver and supplied bymeans of a tube 5 at any desired pressure to the motor, by which thecompressed air in the receiver Ais utilized.

From the foregoing it is seen that the tide-motte consists mainly a pumpfor compressingr air, which pump is operated` by thc float am?. raisedlowered lUO with the same. The compressed air is stored in the receiverfor motive purposes. the receiver acting in the nature of a reservoirfor the Stora e of power, in the same manner as a boiir acts for asteam-motor. The tide-motor is-of comparatively simple and eeCtiveconstruction and can be used in many instances along the coast-line ofthe oceans, being operated automatically by the tides. By transformingthe energy stored up in the receiver into electric energy, the power canbe transmitted to great distances.

l claim: 1. A tide-motor, comprising upright posts anchored to thebottom of the sea, a float guided thereon, an air-compressing pumpsupported on said upright posts, means for locking releasing the pumpfrom said posts by the upward motion of the float, and means forreturning the pump by the downward motion of the float.

2. A tide-m0tor, comprising xcd upright guide-posts, a float guidedthereon, an air pump supported slidingly on said upright posts, meansfor locking the pump to said posts, means for releasing the pump fromsaidposts by the upward motion of the float, means for returning thepump with the downward motion of the float, a receiver for the aircompressed by the pump, and a flexible valved tube between the pump andreceiver.
